Hazardous Area Flowmeters","Oval gear flowmeters are designed to give high performance with a low cost of ownership. These meters are happy measuring simple water like products as well as lubricating fluids. There are several versions; some can have totally non-metallic wetted components, PEEK™, ceramic and a choice of elastomer which makes these the ideal choice for the metering of aggressive chemicals. For hazardous areas either the Namur sensor or the reed switch (simple apparatus) may be used.
